Solitary or cespitose, about 1o cm. high; tubercles elongated, 5 cm. long, somewhat glaucous, 
their axils hairy or naked; spine-areoles with white hairs when young, in age naked; radial spines 
6 to 12, widely spreading, acicular, 2.5 mm. long, white to pale yellow, swollen and darker at base, 
puberulent; central spines 1 to 3, usually solitary, porrect, similar to the radials but usually darker 
with a blackish tip; flowers citron-yellow, 4 to 6 cm. long. 
Type locality: Mexico. 
Distribution: Central Mexico. 
F. Haage jr. in his Choice Cacti lists ten varieties under this species; those not 
accounted for elsewhere are Judwigit and melaleuca. 
Grassner in his Kakteen 1912 and also 1914 listed Mammillaria longimamma var. 
ludwigit. ‘This may be a printer’s error. 
Mammillaria longimamma melaleuca is in the trade (Grassner). Mammillaria longi- 
mamma pseudo-melaleuca is advertised by Haage and Schmidt in their 1922 Catalogue. 
Mammillaria longimamma spinosior (Wochenschr. Gartn. Pflanz. 1: 26. 18 58), credited 
o Link’s Catalogue, but without description, is of this relationship. 
Mammillaria hexacentra Otto and Mammillaria gigantothele (Forster, Handb. Cact. 
183. 1846) were never described. 
Krook (Handb. Cact. 41. 1855) mentions the variety congesta Hortus but gives no 
description. Several varieties of Mammillaria longimamma are in gardens; the following 
are mentioned by Schelle: cristata, compacta (the name cited by Rimpler in 188 5), major, 
laeta, and malaena. 
Mammillaria centricirrha flaviflora is referred by Schumann as a synonym of M. 
melaleuca which we have listed among the synonyms of Dolichothele longimamma. M. alpina 
Martius, mentioned elsewhere, may be of this relationship. -
